OpenEVSE Solar Divert issues with Solar PV, battery SolarEdge

[PaulJordan (Paul J)]

I have since read this thread which confirms my doubt that I cannot sense the battery side of the system as it is all on the DC side:

Solar PV with Battery Monitoring

We’ve just had a Solar PV setup installed along with 2x 3.5Kw batteries. I’ve reviewed the guide here: Solar PV - Guide | OpenEnergyMonitor regarding the setup of the emonpi with solar PV but I’m not entirely sure how I would go about integrating monitoring for the batteries. For those that have this setup, is there a resource you found useful? I’m unsure where to begin with this. Thanks!

At the moment my emonPi and Tx are working in tandem with my solarEdge monitoring system. This isnt efficient but I wanted to start with this to learn how the system then communicates to the openEVSE.

I believe I may be able to use the solarEdge Inverter broadcasted data using a Modbus integration within Home Assistant.

Can anyone recommend how to use the Modbus data feeds to tell the OpenEVSE what it needs to know? I have read so far there are Modbus to MQTT proxys, or I may be able to use Node Red as a similar proxy.
